Wow thank you for such detailed and encouraging feedback ^^
Yeah I was surprised to learn that many ppl find these controls hard, while it's ok to others. My hypothesis is that this difference relates to two distinct categories of map readers: some prefer to rotate them, while others (myself included) prefer constant north up orientation :D that's just a guess though :)
In any case, this is really valuable as I can adjust for it in my future games, so thanks so much!
